	Analogs of cytochalasin B as radiopharmaceuticals for nuclear imaging of trans-membrane glucose transport - Patent ...
		These analogs are identical to cytochalasin B except that the phenyl ring of cytochalasin B is either substituted with a radionuclide or replaced by a radionuclide or a group which includes a radionuclide.
		For nonradioactive analogs of this invention in which R is a phenyl ring bearing an electrophilic activating group, the preferred position of the electrophilic activating group on the phenyl ting is the ortho-position.
		For nonradioactive analogs in which R is a phenyl ring bearing a group replaceable by a radionuclide such as a radioactive halogen, the preferred position of replaceable group on the phenyl ring is the recta-position.

	Title page for ETD etd-050505-090309
		Photochemistry studies of phenyl substituted-1,2,4-thiadiazoles have revealed that 5-phenyl-1,2,4-thiadiazoles 31, 90, 98, 54 and 47 undergo a variety of photochemical reactions including photofragmentation, phototransposition, and photo-ring expansion while irradiation of 3-phenyl-1,2,4-thiadiazoles 46, 105 and 106 leads mainly to the formation of photofragmentation products.
		The photoreactivity of these phenylthiadiazoles in acetonitrile is substantially decreased when the phenyl ring at position 4 is substituted with an electron donating or withdrawing group.
		The relaxed S1 would be the state from which the observed photoproducts originate and the observed fluorescence with the smaller Stokes’ shifts compared with the Stokes’ shifts observed in acetonitrile.

	Phenyl group Summary
		The phenyl group is a ring structure, and as such, it is an aryl group (an organic group derived from an aromatic hydrocarbon with the absence of one hydrogen).
		The phenyl group is unsaturated, that is there are double bonds present that do not have the maximum number of hydrogens attached to them.
		As such, compounds containing the phenyl group are able to participate in all of the reactions of an unsaturated compound.

		Probing the effect of the amidinium group and the phenyl ring on the thermodynamics of binding of benzamidinium chloride to trypsin
		Talhout, Reinskje; Engberts, Jan B.F.N. The effect of the amidinium group and the phenyl ring on the thermodynamics of binding of benzamidinium chloride to the serine proteinase trypsin has been studied using isothermal titration calorimetry.
		Binding of cyclohexylcarboxamidinium chloride and acetamidinium chloride showed that the hydrophobic binding of the phenyl ring in the S1 pocket is primarily entropy-driven and that a rigid, flat hydrophobic binding site for the inhibitor is favourable.

	Radical Cations of Phenyl-Substituted Aziridines: What Are the Conditions for Ring Opening ? (Site not responding. Last check: )
		Depending on the substitution pattern of the aziridines, two different types of radical cations are formed: if the N atom carries a phenyl ring, the aziridine appears to retain its structure after oxidation and the resulting radical cation shows an intense band at 440-480 nm, similar to that of the radical cation of dimethylaniline.
		Conversely, if the N atom carries an alkyl substituent while a phenyl ring is attached to a C-atom of the aziridine, oxidation results in spontaneous ring opening to yield azomethine ylide radical cations which have broad absorptions in the 500-800 nm range.
		The results of quantum chemical calculations confirm the assignment of these species and allow to rationalize the different effects that phenyl rings have if they are attached in different positions of aziridines.

		This is because the phenyl ring is substituted in the para (1,4) position, which allows for flipping of ring, effectively permitting gases to pass through.
		However, the meta-substituted rings in PEI do not allow such flipping, and thus it may be suitable for barrier applications.
		PEI was synthesized for this research using essentially a condensation polymerization of isophthalic acid and ethylene glycol, catalyzed by zinc acetate and antimony trioxide.

		Their structures were differentiated by changing of heteroatom (S or O), substituent in the phenyl ring as well as the type of substituents in polymethine chain.

		It has been stated that the ability of initiation of TMPTA [as 10 vol.% solution in 1-methyl-2-pyrrolidinone (MP)] polymerization depends on the type of heteroatom in the dye molecule, the type of substituent in the phenyl ring, the type of substituent in mezo position in polymethine chain and on borate anion structure.

	Synthesis and phosphodiesterase 5 inhibitory activity of novel phenyl ring modified sildenafil analogues.
		New sildenafil analogues containing an ether ring fused into the phenyl moiety, 6a--d and 7a--d, were efficiently synthesized from the readily available starting materials, 1a--d and 2, in five steps.
		Ab initio calculations indicated that introduction of a cyclic ether to the phenyl group might enhance the co-planarity of the molecule.
		Our study clearly demonstrated that the open chain 2@apos;-alkoxy group of the phenyl ring, although less effective for inducing the co-planarity, seemed to act as a much better lipophilic requirement than the cyclic alkoxy moiety.
